In Reply to: RE: Looking for 60's 6P3S-E's... posted by Michael Samra on February 23, 2017 at 14:52:31
So, to be clear, it has been your experience that the old stock Military 6P3S-E's are tonally superior to the Sovteks, and merit swapping for, perhaps with extreme prejudice? :p

ABSOLUTELY! The SOVTEK is not the same tube.

I wonder if the original sovtek's were just relabed older 6p3s-e's.
Wouldn't doubt it. The ones that came from Bruce in this MOFO sound pretty great, especially biased SUPER HOT and with Mullard f91/f92 long plates in V1, V2, and V3.
It's a question of trying the old 6P3C-E's or perhaps sacrificing real XF2's in this bad boy, as the JJ KT77's sound INSANELY GOOD yet die so quickly...550 B+ and mere 470 ohm screen resistors make for a vicious electrical environment for all but the strongest of valves.
I remember tossing the early Sovtek 5881's in stuff like Ampeg V4b's etc and them holding up to the abuse without issue.
The JJ kt77's were dying in a Dynaco ST70 for me. They'd also drift all over the place. I'm surprised that you got any use at all out of em.
